5-HTP increases serotonin levels in the brain which may positively enhance mood, sleep and weight management! How does NSI® 5-HTP 100 mg work? 5-HTP, or 5-hydroxytryptophan, is a precursor to the neurotransmitter serotonin - which is essential for controlling mood, sleep and pain levels. The body produces 5-HTP from tryptophan, an amino acid found in small amounts in high-protein foods such as chicken, fish, beef and dairy products. It can also be taken in supplemental form, in which case it's extracted from the seeds of the Griffonia simplicifolia plant. 5-HTP is believed to help increase serotonin production in the brain, which may positively influence mood. 5-HTP may also help with other health issues related to serotonin deficiency, including nervousness, body tension and stiffness and head cavity discomfort. Certain elements of sleep are also believed to be affected by 5-HTP. Supplementing may not only assist with falling asleep faster, but also with increasing the duration of dream states (REM sleep) and of deep slumber. 5-HTP may also promote weight management by helping to reduce cravings for sweets and starches, which may help contribute to healthier overall eating habits. For best results and quickest absorption, take 5-HTP on an empty stomach. Do not take 5-HTP for more than three consecutive months without consulting a healthcare practitioner. NSI® 5-HTP 100 mg is better because it:. Ideal for supporting mood, sleep, and weight management. Is available at a better value than other 5-HTP products on the market. . Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"I got this for my husband and he tried taking it in the morning on an empty stomach and then with food. Both ways caused stomach upset. Since he couldn't tolerate it, don't know if it would have been effective for sleep or not."

"I think this product is doing what it's suppose to do - we take it at night and I do seem to be waking more restful. They say that you can sometimes dream a bit more/or maybe just remember more (I don't know), I don't seem to be experiencing this but my husband is for sure - makes for interesting morning conversation.... ha ha... I did meet with a RN/dietician for weightloss counseling and she recommended this as well. Hope this is helpful...."

"I am in my 50s - pre-menopausal, and have begun to have difficulty sleeping, nearly every night. I ordered the 5-HTP and have been really pleased with this product. I take it 30 minutes before I'm ready to be asleep, and have not had any trouble getting to sleep since I started taking it. It's so nice to get a whole night's sleep again!!"

"I have fibromyalgia and osteoarthritis and have always had a problem with sleep, and did not want to use prescription medication for my insomnia, so I tried using 5-HTP and it works I take one 200 mg and I am out like a light for the entire night, though it does take about a half and hour to work, I have been using 5-HTP for around 5 years now and I have my mom useing it to and it works well for her. There are no groggy side effects in the morning when you wake up, and most mornings I find myself waking up feeling more rested. This is only one of the natural things I use for sleep and it works very well."

"I've only been using this for a couple of weeks or so. Since I switched from 1 capsule daily to 2 daily, I've noticed a difference in my appetite and my sugar craving. They've BOTH decreased! I only rated this with a "4" because I want to see the longer term effects before I give it a "5". But so far, so good."

"I started taking this product for for mild depression, to help sleep, and reduce sugar cravings, all of which it does do.....but I was so extremely nauseous the first two weeks and had absolutely no appetite at all. Also decreased libido, which is so unlikely for me.....anyway, yes, I had NO sugar cravings and I have the worlds worst sweet tooth.....but my complete lack of desire to eat and extreme nausea is not worth it. Also, you do sleep very well, but I always felt out of it the next day....going back to just Melatonin and Omega 3's and B Vitamins for mood support."
